Abstract
Exchange mutual -inductor detection circuitry, it includes controller, temperature sensor, alarm and fan, the equal electrically connected controller of temperature sensor, alarm and fan, temperature sensor electrically connected controller for real -time detection exchanges the temperature of mutual -inductor, and the temperature electric signal that answers of generating pair, the controller is used for carrying out the comparison with temperature electric signal with predetermined the first temperature threshold value and the second temperature threshold value, when temperature electric signal is higher than the first temperature threshold value and is less than the second temperature threshold value, and control fan start -up work to give and exchange the mutual -inductor heat dissipation, when temperature electric signal was higher than the second temperature threshold value, the drive alarm sent alarm signal, wherein, the first temperature threshold value is less than the second temperature threshold value. The utility model discloses but real -time detection exchanges the temperature of mutual -inductor, dispels the heat through the fan when the temperature is higher to the cooling, and reach uncontrollable degree when the temperature, report to the police safe and reliable through the alarm.
Description
Technical field
The utility model relates to a kind of AC mutual inductor detection circuit.
Background technology
In the circuit of generating, power transformation, transmission of electricity, distribution and electricity consumption, size of current great disparity, has from a few peace to a little Wan An.Need to be converted to low-voltage current for ease of measurement, protection and control, in addition, the voltage on circuit generally all higher as direct measurement is breakneck.Thus, current transformer plays current transformation and electrical isolation effect.
Because D.C mutual-inductor plays the transformation of high voltage and current and low-voltage current, Long-Time Service, D.C mutual-inductor there will be excess temperature situation, its inside of severe patient smolders or smelly, because element is less, staff often can not Timeliness coverage, thus likely causes electrical fire.
Utility model content
For the deficiencies in the prior art, the utility model is intended to provide a kind of AC mutual inductor detection circuit solved the problems of the technologies described above.
For achieving the above object, the utility model adopts following technical scheme:
A kind of AC mutual inductor detection circuit, it comprises controller, temperature sensor, alarm and fan;
Temperature sensor, alarm and fan are all electrically connected controller; Temperature sensor is used for the temperature detecting D.C mutual-inductor in real time, and generates corresponding temperature signal; Controller is used for temperature signal and the first temperature threshold preset and the second temperature threshold to compare, and when temperature signal is higher than the first temperature threshold and lower than the second temperature threshold, controls starting fan work, to dispel the heat to D.C mutual-inductor; When temperature signal is higher than the second temperature threshold, alarm is driven to send alerting signal; Wherein, the first temperature threshold is less than the second temperature threshold.
Preferably, this temperature sensor is thermistor.
Preferably, alarm is the light emitting diode and the hummer that are electrically connected controller.
The beneficial effects of the utility model are at least as follows:
The utility model can detect the temperature of D.C mutual-inductor in real time, is dispelled the heat by fan when temperature is higher, to lower the temperature, and when temperature reaches uncontrollable degree, now, inside has likely smoldered, when fan cannot reduce its internal temperature, by alarm equipment alarm, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the electrical connection schematic diagram of the better embodiment of the utility model AC mutual inductor detection circuit.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
Refer to Fig. 1, the utility model relates to a kind of AC mutual inductor detection circuit, and its better embodiment comprises controller, temperature sensor, alarm and fan;
Temperature sensor, alarm and fan are all electrically connected controller;
Temperature sensor is used for the temperature detecting D.C mutual-inductor in real time, and generates corresponding temperature signal;
Preferably, this temperature sensor is thermistor, to reduce costs.
Controller is used for temperature signal and the first temperature threshold preset and the second temperature threshold to compare, and when temperature signal is higher than the first temperature threshold and lower than the second temperature threshold, controls starting fan work, to dispel the heat to D.C mutual-inductor; When temperature signal is higher than the second temperature threshold, drives alarm to send alerting signal, to remind the excess temperature situation of staff's D.C mutual-inductor out of control, rush to repair in time;
Wherein, the first temperature threshold is less than the second temperature threshold.
The utility model can detect the temperature of D.C mutual-inductor in real time, is dispelled the heat by fan when temperature is higher, to lower the temperature, and when temperature reaches uncontrollable degree, now, inside has likely smoldered, when fan cannot reduce its internal temperature, by alarm equipment alarm, safe and reliable.
Preferably, alarm is the light emitting diode and the hummer that are electrically connected controller.
For a person skilled in the art, according to technical scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the utility model claim.
